The beauty of roundness-unlock the core value of "roundness" in the field of industrial manufacturing and design

Precision measurement, the achievement of every perfect circular contour

The Science Behind Curves | Decoding the Precision Language of "Circle" in Industrial Production

When we see a smooth metal bearing, a high-speed engine spindle, or an attitude-adjusting gyroscope for space probes, it may be difficult to imagine that one of their common core quality standards is actually "roundness". This is not only a geometric concept, but also a basic element to ensure smooth mechanical movement and reduce wear and tear. Even micrometre-level deviations can trigger a chain reaction leading to overall system failure.

the contest between millimeters | why do top factories have to haggle over "roundness"

In the increasingly competitive global manufacturing environment, more and more companies are beginning to realize the value of high precision. For example, in the gearbox housing processing line, the manufacturer will use ultra-fine grinding process to ensure that each gear has a nearly ideal circular tooth profile, while in the aircraft engine blade casting process, through the whole closed-loop monitoring technology to prevent the edge distortion caused by thermal deformation.

With the development and progress of metrology, we can now use advanced equipment such as three-coordinate measuring machines (CMM) and optical imaging instruments to achieve contactless scanning and capture the shape characteristics of the workpiece. This kind of instrument can build a three-dimensional model in a very short time, and combine the software algorithm to accurately calculate the specific deviation from the theoretical value, to provide a reliable basis for improving the production process.

Although each industry is in the pursuit of higher shape accuracy, but their focus is not the same. For example, the automotive industry focuses on the fatigue life performance of rolling elements in the transmission mechanism; the aerospace sector pays more attention to the consistency level of navigation flywheel dynamic balance; as for micro-motor motor manufacturers, they tend to focus on whether the core rotor air gap distribution is uniform enough to obtain the best torque output efficiency.

Friends who are first involved in the relevant supply chain may be confused by the variety of product specification sheets. In fact, as long as you keep in mind three key points, you can preliminarily judge the authenticity of the samples provided: first, pay attention to whether the sampling site is representative; Secondly, check the original test date and its duration span; Finally, it is necessary to verify whether the reporting unit itself holds the relevant qualification certificate issued by the National Accreditation Commission.

future trend outlook | what changes will "roundness" management usher in under the blessing of artificial intelligence

Looking forward to the next few years, "intelligent big data" will become the main source of power to drive the entire industry forward. Imagine such a scenario: AI has already issued a warning in advance to remind relevant personnel to intervene in the adjustment before a node on a certain production line shows signs of abnormal fluctuation; At the same time, the cloud platform is used to share the resources of the unified value standard database of each factory area, making the global cooperation closer and more efficient.
